Just wanted to know if it is possible to specify a time zone that has
no winter time shift whole year?

[snip]

A few weeks ago, my Lenny system switched over from displaying time in MST
(Mountain Standard Time) to MDT (Mountain Daylight Time). It did this, I
believe, because the switch-over is mandated in the official locale coding
for this region (Colorado). I would like to now how to take a pass on this
switch-over part of the local locale. And how to do it ahead of time, so
that for me, I don't have to find an unwanted task of undoing a unwanted

change waiting on a Sunday morning. My version of what I think OP was
asking for is a variant of locale that does not honor local mandates for
switching to and from summer-time. It is very much a cultural thing.

Silly question why would you want to not follow local time ?

I do follow local *standard* time, which is the local time for the west

105deg meridian. I live in Lafayette, Colorado, which is at 105deg.6'
west. Local time here is 24 seconds delayed from local time at the
central meridian of this zone, and about a minute later than the local
time for Denver. That is close enough for me. I'm really not an
extremist ;-)

MDT is active for 7 months and 3 weeks, which means that it is the
de facto standard.
